I'm trying to run a small winform app (code is C#) on WinPE (latest build 14393). Calling the exe starts the application, but the GUI doesn't show up. I injected .NET to PE via dism, so this is not the problem. Found a post where s.o. had the same problem, but I don't understand the solution. .NET GUI Not Displaying in WinPE I don't want to run powershell, because this would size up the PE boot.wim even more. It should be kept as small as possible. Any ideas?

- To reduce its size, Windows PE includes only a subset of the available Win32 application programming interfaces (APIs). I/O (disk and network) and core Win32 APIs are included. - **Windows PE does not support the Microsoft .NET Framework or the Common Language Runtime (CLR).** – Softe Eng Aug 04 '16 at 12:28

.NET framework is available as an optional package for WinPE, delivered with the ADK. As I wrote above, this package is already installed. **It is not correct, that .NET is not supported!** – Mahobo Aug 04 '16 at 12:46

I am telling you what was stated by Microsoft, not by me.[Read Here](https://technet.microsoft.com/en-us/library/cc766093(v=ws.10).aspx) – Softe Eng Aug 04 '16 at 12:47

Your link is related to WinPE 2.0, which is a very early version. In those times, there was no .NET support in PE. As I stated in my question, I'm using WinPE 14393 what is the latest build. – Mahobo Aug 04 '16 at 13:16

Since your app uses .Net and windows.forms namespace. You need to add the dependant packages when you build for WinPE – Softe Eng Aug 04 '16 at 13:19

walking through all those MS sites related to WinPE, I found the hint to success in starting my app. It works!
Dependencies: Install WinPE-WMI before you install WinPE-NetFX.
